Description
2.1
Product overview
The PSS
®
Buddy Breather is a second medium-pressure connector that
integrates into the medium-pressure system of a Dräger PSS
®
Series
breathing apparatus. It is connected into a port on the pressure reducer
and provides the wearer with two connectors as follows:
● An outlet connector (female quick-connect coupling) is used for the
supply of air to a second person for the purpose of rescue.
● An inlet connector (male quick-connect coupling) is used for the supply
of air from an alternative medium-pressure air source for
decontamination.
There is a one-way valve in the inlet connector of the PSS
®
Buddy
Breather that normally blocks outlet air flow from the connector. A safety
feature is that the outlet connector of the PSS
®
Buddy Breather has an
actuator coupling (AC) that overrides the one-way valve if two PSS
®
Buddy
Breathers are connected together. This ensures that if a second PSS
®
Buddy Breather is accidentally reverse connected during a rescue, air is
still supplied to the second person.
2.2
Intended use
The PSS
®
Buddy Breather is intended for use with Dräger PSS
®
Series
breathing apparatus, to provide the wearer with rescue and/or
decontamination capabilities.
Lung demand valves, rescue hoods and other accessories used with these
products must be certified Dräger components, assembled in an approved
configuration. Contact Dräger for further information.
2.3

Use
WARNING
The detailed procedures described in these instructions for use
shall be followed in order to avoid exposure to higher risks (e.g. air
loss).
Before using the PSS
®
Buddy Breather it must be properly assembled and
tested on a Dräger PSS
®
breathing apparatus. Assembly instructions (see
Section 7) are included in these instructions for use for trained service
personnel only.
3.1
Preparation for use
1. Prepare the breathing apparatus for use, including all pre-operational
and functional testing, and don the breathing apparatus (see the
instructions for use supplied with the breathing apparatus).
2. When required, carry out the decontamination procedure (see
Section 3.2) or rescue procedure (see Section 3.3).

3.2
Decontamination procedure
WARNING
Air quality for compressed air systems must conform to EN12021;
do not use oxygen or oxygen enriched air.
The decontamination air supply pressure to the PSS
®
Buddy
Breather must not exceed 10 bar. Do not attempt to connect high-
pressure air.
Using an air supply that does not comply with the air quality,
pressure and flow requirements could result in death or serious
injury for the user.
NOTICE
It is recommended that a second person monitors and maintains
the decontamination air supply throughout the decontamination
procedure.
Decontamination air supply pressure and flow:
Operating requirement: 6 bar to 10 bar at an air flow rate of at least
550 litres/minute.
1. Ensure that the decontamination air supply complies with the air
quality, pressure and flow requirements.
2. Close any relief valves fitted, and then fully open the valve of the
decontamination air supply to pressurize the system.
3. Remove the PSS
®
Buddy Breather from the pouch.
4. Disconnect the protection cap from the inlet connector (male coupling)
of the PSS
®
Buddy Breather and connect the hose from the
decontamination air supply.
WARNING
Fully close the cylinder valve of the breathing apparatus to avoid
air loss from the cylinder during decontamination.
If there is any disruption to the decontamination air supply, reopen
the breathing apparatus cylinder valve and immediately
disconnect the decontamination air supply from the breathing
apparatus.
5. Breathe normally and fully close the cylinder valve of the breathing
apparatus (see the instructions for use supplied with the breathing
apparatus).
NOTICE
If the pressure of the decontamination air supply is higher than the
medium pressure of the breathing apparatus, air may be trapped
on the high-pressure side of the reducer. The gauge of the
apparatus will continue to show a reading and the whistle will
activate as normal as air escapes. Take several short deep
breaths or briefly press the centre of rubber cover of the lung
demand valve to release the trapped air.
6. When the decontamination procedure is complete, remove the
breathing apparatus using one of the following methods:
Method 1
– When the wearer is in a safe area (surrounding air is safe to
breathe and all contamination sources have been removed).
1. Lift and pull forward on each of the bottom buckles of the face mask
straps.
2. Positive-pressure systems only – as the seal between the face and the
mask is broken, press the reset button of the lung demand valve.
3. Remove the face mask.
4. Disconnect the decontamination air supply from the PSS
®
Buddy
Breather.
5. Refit the protection cap, coil the hose and place the PSS
®
Buddy
Breather in the pouch.

6. Press the rubber cover at the front of the lung demand valve to vent
the system fully. Press the reset button of a positive-pressure lung
demand valve.
7. Remove the breathing apparatus (see the instructions for use supplied
with the breathing apparatus).
Method 2
– When the wearer is in an unsafe area (surrounding air is not
safe to breathe or there are, or may be, contamination sources in the area).
WARNING
The duration of the breathing apparatus air supply is dependent on
the volume of air in the cylinder. The wearer commences breathing
from the air cylinder when the cylinder valve is opened and the
decontamination air supply is disconnected.
1. Slowly and fully open the cylinder valve of the self contained breathing
apparatus.
2. Disconnect the decontamination air supply from the PSS
®
Buddy
Breather.
3. Refit the protection cap, coil the hose and place the PSS
®
Buddy
Breather in the pouch.
4. Breathe normally and proceed to a safe area.
5. Once in a safe area, remove the breathing apparatus (see the
instructions for use supplied with the breathing apparatus).
3.3
Rescue procedure
WARNING
Using the PSS
®
Buddy Breather for a rescue will reduce the
duration of the air supply from the cylinder. Fully assess the risks,
considering both the wearer and the person in distress, before
carrying out a rescue.
NOTICE
There is a one-way valve in the inlet connector (male coupling) of
the PSS
®
Buddy Breather that normally blocks outlet air flow from
the connector. Do not use the inlet connector of the PSS
®
Buddy
Breather as an air outlet for rescue.
For a rescue operation, the PSS
®
Buddy Breather is connected to a lung
demand valve and face mask combination, a rescue hood, or a second
PSS
®
Buddy Breather. The recommended rescue breathing equipment is:
● PSS
®
Rescue Hood, or
● Dräger rescue lung demand valve (N-type with 1.75 m hose) and
Dräger face mask (RA-type – normal pressure), or
● PSS
®
Buddy Breather.
The PSS
®
Buddy Breather can also be used for unplanned assistance to
a second wearer of compatible breathing apparatus. Products that are
compatible with the PSS
®
Buddy Breather are Dräger Plus and PSS
®
Series lung demand valves (A, AE, N and ESA), when they are connected
to a face mask.
1. At the incident rescue point, remove the PSS
®
Buddy Breather from
the pouch and disconnect the protection cap from the outlet connector
(female coupling). Connect a lung demand valve and face mask
combination, a rescue hood, or a second PSS
®
Buddy Breather to the
coupling.
2. Proceed immediately to a safe area.
3. Once in a safe area, remove the breathing apparatus (see the
instructions for use supplied with the breathing apparatus).
4. Disconnect the male coupling from the outlet connector of the PSS
®
Buddy Breather and refit the protection cap. Coil the hose and place
the PSS
®
Buddy Breather in the pouch.
3.4
After use
Carry out the after use tasks detailed in the associated breathing
apparatus instructions for use.
4
Troubleshooting
There are no user troubleshooting tasks on the PSS
®
Buddy Breather.
Refer to the troubleshooting information in the associated breathing
apparatus instructions for use, or contact Dräger or service personnel for
further information.
5
Maintenance
Carry out routine maintenance, including cleaning and disinfecting, after
each use as defined in the associated breathing apparatus instructions for
use.
6
Storage
Store the equipment in a cool dry environment, free from dust and dirt. Do
not expose to direct sunlight.
